The field of cryptography is undergoing a significant transformation with the advent of quantum computing, which poses a substantial threat to traditional cryptographic systems. Researchers are actively exploring post-quantum cryptography (PQC) solutions to ensure a secure transition to a quantum-resistant cryptographic landscape. Notably, the integration of PQC algorithms into blockchain technology is a key area of focus, as blockchain's reliance on cryptographic protocols makes it vulnerable to quantum attacks. Recent studies have highlighted the challenges and opportunities in developing post-quantum blockchains, including the need for standardized PQC algorithms and optimized parameter settings. Innovations in blockchain database design are also emerging, with proposals for forkless blockchain databases showing significant improvements in storage and throughput. Overall, the field is moving towards a more secure and quantum-resistant future, with a growing emphasis on PQC and blockchain security. Noteworthy papers include: Tight Quantum-Security Bounds and Parameter Optimization for SPHINCS+ and NTRU, which establishes tight security bounds for two NIST PQC finalists, and Efficient Forkless Blockchain Databases, which proposes a novel database design for forkless blockchains.
